55 Claims.

This invention, while directed generally to laundry machines in which clothes pass between operating rollers, is exemplified herein as a clothes wringer.

Power wringers involve many problems. In the ordinary operation of a clothes wringer the person using the wringer is concerned with several functional requirements.

Objects of the invention are to satisfy these requirements, and involve the following features:

The control-starting, stopping and reversing-of the driving mechanism.

The control of the pressure on the rolls involving a quick or safety release of that pressure.

The resetting of the pressure and preferably, also, a normal adjustment of the pressure.

Movability of the wringer to different adjusted positions of use, commonlyreferred to as index ing.

Wringers as now commonly in use are usually provided with one or the other of two general schemes going to the safety of the operation. In one of these, provision is made for stopping the rolls so as to prevent a further injuring of the part caught and in some cases actually reversing the roll so as not to limit the indrawing action but also to expel the part caught. The othertype of safety device provides for releasing the pressure on the rolls so that notwithstanding continued rotation, the pressure being released, further serious injury isobviated or the injury very greatly reduced.

Various means for actuating these safety devices have been developed, some of them providing a manual tripping or actuating mechanism which is actuated by the operator to initiate a relief action.

In the present invention means are provided for manual actuation of both release devices and for resetting them, both of these'safety devices being actuated or responsive to a single releasing effort by the operator.

The present invention contemplates, also, a second method of actuating the release devices, this method being usually referred to in the art as the instinctive method of release. An operator when caught in the wringer instinctively draws back in the effort to prevent further indrawing of the part engaged to pull the part free from the engagement. In the present invention the wringer frame is mounted to respond to such a pull (or push) and to eflectboth a release of the pressure and a release or disengagement on the rolls is released but the continued rotation of the rolls is also stopped.

The wringer is provided with an indexing mechanism by which the wringer is locked at different angles. As developed in the present wringer this locking of the indexing mechanism is accomplished automatically with the resetting of the driving mechanism and the wringer pressure.

In order that the wringer itself may be positioned so as to yield in response to an instinctive pull of the operator when caught it is yieldingly held at the'index position so that it can respond to such a pull and thus effect a release.

The wringer, therefore, must be positioned so as to permit this yielding movement and if it is to be responsive to a push as well as a pull it must be centered with relation to its wringing position and yieldingly held at that position with sufiicient force to prevent accidental movement in the ordinary wringer operation. In the present device this centering and this 'yiel'ding holding of the wringer in its operating position are automatically accomplished by the resetting mechanism as it resets the pressure and resets the driving mechanism. Inasmuch as in the feeding of clothes to the wringer it is more apt to involve the pushing of the wringer away from the operator while the instinctive action of a user caught in the rolls is usually a pull rather than a push, it is desirable to make the releasing movement of the wringer more sensitive to a. pull than a push by the operator. In the presventinvention this is accomplished.

' operative in either direction, the rotative action of the driving means so that not only the pressure of the rod relocking the indexing device, resetting the yielding centering device, resetting the pressure on the rolls, and re-engaging the driving mechanism. Further features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings as follows:

Fig. 12 shows an end view of a fragment of a wringer frame.

"I marks the head of the wringer in which the I driving gears are arranged. The head is provided with a swivel extension H which is received in the upper end of the usual post l2 which carries the wringer. A vertical drive shaft l3 extends upwardly through the post from some source of power, ordinarily the-power that drives the washing machine to which the wringer is attached. This shaft extends through bearing supports I4 and 15 at the bottom and top of the head respectively.

Bevel gears 16 and flare journaled on the shaft l3 and these gears continuously mesh a" bevel gear Ill. The gear l8 has an extended hub 44 which is journaled in a bearing formed in a frame I9. The frame has the connected arms 20 and 2| and these arms are carried by a gear frame support 22, the support 22 being swiveled in the extension ll of the head and the arms 20 and 2! being rotatively related to the shaft l3. With this arrangement the wringer head may be swung relatively to the gear frame and the head swung relatively to the post [2 for indexing.

A clutch block 23 has detents 2341 on its ends I adapted to engage detents Ilia and I'Ia on the bevel gears l6 and 11. The block is splined on the shaft I3 so that while'it is locked against rotation on the shaft it is movable axially on the shaft to set and release the clutches. The block has a circumferential groove which receives the bifurcated ends of an operating bar 2i. The operating bar terminates in an eccentric strap 24a which is actuated by a crank 25a. fixed on a shaft 25. The shaft 25 is journaled in abearing 26 extending from the head and is provided with a manually operative lever arm 21 at the inner end of the head by means of which the shaft may be rocked, the crank operated, the bar 24 actuated, and the clutch block moved to release the driving connection or reverse the same in the usual manner. The shaft 25 is continued or prolooted by means of a shaft 28, the shaft 28 being connected with the shaft 25 by a ring 29, the ring encircling the vertical shaft i3. permits of placing the shafts 28 and 25 at the direct center of the wringer and permits of a controlling shaft extending from end to end of the wringer.

In order to index the wringer, that is. lock the head and consequently the wringer frame with the post 12, I provide the following mechanism: A pawl 30 is pivoted on the gear frame support 22 by means of a pivot pin 3|. The pawl extends through a slot 16a in the swivel extension H Thus the ring eumferential length to permit of pivotal movement of the swivel extension. The pawl has an upper face 30a which is adapted to be engaged by either of the cam surfaces 33 arranged on the face of the cam plate 32, the support 22 having the notch 22a affording clearance for the cam plate. The cam plate 32 is fixed on the shaft 25 and is, therefore, adapted to be rocked by either the shaft 25 or shaft 28.

This pawl and cam mechanism effects two important functions: The cam forces the pawl into wedging engagement with the inner surface of the post, locking the gear frame rigidly with the post. At the same time the frictional engagement of the engaged cam surfaces 33 with the surface 30aof the pawl yieldingly secures the head against movement in the normal wringing operation but permits a yielding movement in response to an instinctive pull of an operator. This variation in engagement of the pawl with the post and the yielding resistance afforded by the cam on the surface 30a are brought about by the fact of the wedging arrangement of the engaging surface of the pawl with the post, the greater leverage afforded at the engaging surface 3lla over that of the engaging surface of the pawl with relation to the pivot, and also the difference in radial position of the engaging surfaces between the pawl and the post and the friction surfaces of the cam 33 and the surface 38a, this difference being sumciently marked to substantially lock the gear frame at the index position and yieldingly hold the wringer head at the set or operative position. As will be hereinafter explained, when the wringer is pulled for instinctive release the engaged cam 33 rolls out of engagement with the turning of the shaft 25 and thus makes the instinctive pull movement more sensitive than a release from pushing the wringer.

The main wringer frame has a base 34, and side stiles 34a. The base has projections 34b and 34c carrying bearings for the rod 28. The base 34 also has the flaring front and rear cross members 35 connected by a trough 36 provided with a drainage opening 31 (see Fig. 4).

A water board 38 is pivotally mounted at 38 on the control rod 28. Flipper arms 40 and 4| are fixed on the shaft 28, these arms being spaced relatively to the water-board to afford some lost motion, but to swing the water board to reverse position when the control rod 28 is thrown to reverse position.

The wringer is provided with a lower wringer roll 42. The wringer roll has a shaft 42a and this shaft is journaled in bearings fixed in stiles 34a. The shaft 42a is connected by a flexible coupling 43 with the hub 44 of the gear 13. The flexible coupling 43 is made up of a series of discs connected at separated points, each pair of discs being connected at oif-set points from that of the adjacent pair of discs in the well known manner of flexible couplings. This flexible coupling provides sufficient flexibility to permit the wringer to swing relatively to the gear frame and post I2 in response to an instinctive pull of the operator, and tends to maintain the wringer on center.

of the head, the outer surface of the pawl gradually increasing the radial spacing from the pivot 3| providing a wedging engagement with the post. The inner side of the slot 10a has sufficient cir- A top frame member 45 is carried by the main frame and is free to move upwardly relatively thereto. An upper r011 46 is mounted in the top frame member and provided with the usual bearings 46a (Fig. 1) which are slidingly mounted in the top frame member. The assembly of the upper roll and its bearings are retained by cross screws "a in the top frame and pressure is exerted on the rolls from the top frame by means of a spring 41 the ends of which rest on the top bearings. nected at either side as at 56 to downwardly projecting plates 56, the same perhaps being best shown in Figs. 3 and 11. The upper frame and its attached parts may be swung on the pivot 50 either to the front or rear, as shown in broken lines in Fig. 4, so that by removing the screws 45a, the upper roll with its bearings 46a may be removed from the upper frame. In the dotted line position (Fig. 4), the upper roll has been removed. Guard plates Mo are arranged at the ends of the rolls and are journalled on the shaft of the lower roll. When the upper frame is swung out, the guard plate can swing out to the position shown in dotted lines in Fig. 4 to permit the release of the upper roll. The pressure member is adjusted by screw 68 arranged in the top frame member and secured to the spring Q! in the usual manner (see 'Fig. 4). A guide bar Mb is secured to the guard plates and extends in front of the bite of the rolls on one side of the wringer.

The wringer head is provided with a flange where it engages the wringer frame and screws 49 extend through this flange into the wringer frame, thus rigidly securing the head to the wringer frame.

The top frame member is secured to plates 5| (one at each end of the wringer) by screws 56. These plates extend downwardly through the top frame member and stiles Zita to the bottom of the wringer and are slidingly mounted in the stiles 34a. The lower ends of the plates 51 are enlarged at 52 and are provided with cam slots 53.

Rock arms 56 are mounted on the shaft 26 and are locked with the shaft by pins 54 and 55. These arms have at each end, heads 51, in which are mounted pins 58 and 59 which are adapted to engage the cam surfaces of the slots 53.

The plates 5| are provided with slots 66 through which the rod 26 extends and this provides the clearance of the up and down movement for the plates 5i.

When the rod 28 is swung to its extreme in either direction one of the pins 58 or 59 at each end of the wringer is brought into engagement with the cam surface at the bottom of the slot 53 and thus depresses the plates 5| and with them the top frame member 45, bringing the frame down to set position and restoring the pressure through the spring 43'! on the rolls. It will be noted that in this set position the pin (59 as shown in Fig. 3) is directly below the rod 28, so that it may be said to be on center and not only is held in this position by the frictional engagement of the pin 59 with the cam surface of the slot but is locked by the engagement of the cam surfaces 33 on the pawl 30. When the lever arm 21 is swung, therefore, it is only necessary to start the pin 59 to carry it off center and from there on the pressure effort of the spring 41 continues the rotative movement of the rod 28' until the pressure of the spring 41 is relieved. The sprin 41, 7 therefore, through its energy operating through the rod 28, completes the release of the cams 33 and consequently completes the release of the indexing of the wringer, and also supplies energy to throw the clutch block 23 to neutral position midway between the gears l6, I! at which time the clutch control lever 21 is moved to the dotted line position of Fig. 1. When it is desired to reset the pressure on the spring it is only necessary to rock the arm or lever 21, thus swinging the rod 26 to bring either the pin 58 or The upper frame 65 is pivotally conv 59 to the position in the alignment with the rod 28. This draws down the plates, sets the top frame member and resets the pressure on the spring. This is accomplished without changing the pressure adjustment through the screw 48.

Springs 6| have their upper ends secured to projections 62 extending inwardly from plates secured to the lower frame, and in their lower ends to pins 63 secured in the plates 5| so that when the plates are released from the action of the pins 58 or 59 the springs 6i carry the top frame upwardly to the limit of its movement even though the pressure exerted by the spring 4'! has ceased to operate.

In order to more securely lock the frame members together when the wringer is in set position the sides of the upper frame are provided with projections 45a which extend into notches 34d at the tops of the stiles 34a. This positively centers and holds the upper frame in register with the lower frame, thus supplementing the plates 5! in holding the parts rigidly with the wringer in set position.

In order that control of the wringer may be more convenientlyaccessible I prefer to provide a lever 64 on the outer end of the rod 28 so that the control and resetting of the wringer may be accomplished by either hand and from either end of the wringer.

In order that the safety devices may be actuated through an instinctive pull on the wringer the following mechanism is provided: A collar 65 is fixed on the shaft 28 within the head "I the walls of the head being projected at Nib to provide space for the collar 65, the projection having a cavity permitting the swinging of the head rela tively to the shaft 28 and hub 65, Arms 66 project from the collar 65. The frame I9 is provided with a slot 61. The vertical side walls 61a of the slot form operating surfaces engaged by the arms 66 (see Figs. 6, 8-, 9, and 10). As the resetting levers 21 and 64 are swung the arms 66 are swung into engagement with the surfaces 61a and center the wringer head, and consequently the wringer, with the frame 19. This same setting action, it will be remembered, locks the frame with the post, but the yielding nature of the engagement of the cams 33 with the pawl 36 permits movement of the wringer on the post in this centering operation so that as the drive is reset through'the rotation of the rod for drive in either direction the arms 66 swing tothe opposed surfaces G'la and positively center the wringer with relation to the frame and post. If the wringer is swung either forward or back, one or the other of the arms 66 is forced by one of the moving surfaces 61a (the frame i9 being held by the lock at the'lndex and the head in being slotted at Illa) toward the upright or vertical direction and this movement of the arms 66 rock the arm 28 starting the release movement by moving the pin 59 off center with the resulting neutralizing movement of the clutch, release of the index, the release of the wringer with relation to the gear frame, and release of the pressure on the rolls. It will be noted if the wringer is pulled (moved to the right in Fig. 3) and the cam 33 being at the opposite side of the axis of the head moves toward the left and the counter-clockwise rotation of shafts 26 and 25 swinging pin 59 off center results in a rolling movement of fcam 33 out of engagement while a push of the wringer (movement toward the left in Fig. 3) also moves the shaft in a counter-clockwise direction, but the cam 33 slides on the surface 300 counter to the direction of movement. Thus the instinctive pull release movement is sensitive while the push release movement is less sensitive and therefore less liable to eifect an accidental release movement through the feeding of clothes to the wringer.

It will be seen, therefore, that in this structure through this single main operating member, namely, the rod 28, the entire control of the safety devices, pressure and drive, is accomplished. With this simple mechanism it will be noted that all the controls are carried through the bottom of the wringer and are responsive to the operation of a single member, namely the operating rod, actuated consciously through the operating handles or instinctively through a pull on the wringer. This is responsive to the manual control through the handles or an instinctive control through swinging of the head, and through the actual operation of this rod the pressure on the wringer may be reset, the gears set to give the rolls either direction of movement, the indexing locked, the wringer yieldingly centered, the instinctive release mechanism positioned to be operated by movement of the wringer either forward or back, and the water board is automatically resetto operate with relation to direction of movement of the rolls. The manual release levers are arranged at both ends of the wringer so that the operator may handleeither onethat may be the more convenient. The resetting mechanism is utilized in the release operation, but the resetting operation and release operation may be accomplished by different means, manually by the lever, or instinctively through the action of the arms 66.

It will be noted that the engagement of the pin 59 in set position is practically point engagement and that under the ordinary jar of the wringer is unstable and that the holding means incident to the member 32 not only holds the mechanism in set position, but also under normal conditions would be effective for releasing the pressure means upon a movement of the wringer. The parts 6566 supplement the holding means in this regard and not only, under ordinary conditions, effect a release but go farther and compel a movement of the rod and therefore assure a positive release.

In the operation of the wringer, starting with set position, should the operator become caught in the rolls, a mere pull or push, ordinarily a pull, swings the wringer frame. This compels a rotation of the releasing rod positively accomplished by the arms 68 and the action of the cam plate 32 in carrying the pin 58 or 59, as the'case may be, of! center and thus releasing the pressure on the rolls. This same action of the rod acting through thecrank or eccentric 25a and bar 24 moves the clutch to neutral. This same action releases the indexing lock.

To reset the wringer; all that is necessary is to operate one of the levers 21 and 64, thus rotating the rod. This. through the rock arms 56, resets the pressure, through the eccentric 25a and bar 24, sets the clutch in driving relation, compels a movement of the wringer to centered position, locks the wringer in this position, and locks the index.

It will be noted that after the release, the detents a free the top part of the frame so that application 505,318 filed by me December 29, 1930, for improvement in Wringers.
